Abstract
An electrostatic sensor system is carried on two relatively movable objects between which a person can be disposed for determining the presence or absence of the person between the objects. One electrode on is one of the objects and first and second electrodes are on the other of the objects. A controller or control means applies an electrical charge to the one electrode on one object or the first and second electrodes on the other object, determines a coupling factor between the one electrode on the one object and the first electrode arranged on the other object and a coupling factor between the electrode arranged on one object and the second electrode arranged on the other object can be detected, and compares the two coupling factors with one another.
